turbo cam upgrade
I been tossing around the idea of a cam swap in my 5.3 t76 build . I emailed speed inc and they suggested the tu1 for quicker spool and a good street cam over the tu2 . Im not debating the cam size but do you all think the cam is worth the expense. would also get the springs and push rods to match it.
How much of a gain over a stock cam would i get roughly.
Thanks for any opinions
